TO ALL W-HOM IT MAY CONCERN: Y p

Beit knownwthatZI, CALLR GRESIUCHNA, of New York, county and State of New York, have invented 'a new and useful Improvement in Apparatus for Distilling and-Rectifying and I do hereby declare that the'following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing- Figure '1 represents-a vertical central section of this invention.

Figure 2 is a horizontal section thereof. V

imilar letters indicate corresponding parts.

- This invention relates to au improvement in an apparatus'for rectifying distilled liquids, on which a patent was granted to myself and L. Jarchow, July'2, 1867, No. 66,323. v

Said apparatus 'consists of a receiver, A, which communicates by the pipe B with thestill. This pipe extends up through the bottom ofthe receiver, and its inner end isccvered by a cap, C, which tits loosely over it, and which is open at the bottom, being supported hy suitable legs or strips'a, so that the vapors rising Vthrough the pipe`B are compelled by the cap to turn down in order to escape at the bottom edge of said cap.

In passing down through the cap, and up again after having escaped from the same, the vapors are compelled to travel through the low-wine which accumulates at the bottom of the reeiver, and the depth of which in the receiver is determined by the overdow-pipe b, which may be made to connect with the still or with any other suitable vessel. As the vapors rise in the receiver, they strike the under surface offthe circular dish-D, the diameter of whiehis somewhat less th'authe inner diameter of the receiver, so as to permit the vapors to pass up through the annular space between the dish and the receiver, as indicated by arrows in iig. 1 of the drawing.

The dish D is suspended from the top plate ofthe receiver by pins or studs c, and itis provided with a central depression, d, intended to receive the low-wine resulting from the condensation of a portion of the vapors during their passage through the space between the dish and the top plate of the receiver. From the bottom part of the depression el extend` two (more or less,) pipes, e, throughwhch -the lowwine accumulating in said dcpres sions runs down into the receiver A. The top plate of the receiver is depressed towards its centre, and the edges of the receiver project above said top plate so as to form a vessel, E, capable of holding a quantity of water, whereby the condensation of a portion of the vapors coming in contact with the top plate of the receiver is facilitated. The water in the vessel E is supplied fromabovc, as will be hereinafter described, and the sur-A plus water vpasses off through a suitable waste-pipe. From the centre of 'the top plate .of the receiver rises a,

pipe, F, through which the vapors pass up into thc rectifier G. This-rectifier is provided with a seriesf circular dishes, I)l DZ D3,V Src., similar te the' dish D in the'rectiier, with the exception, that their central depressions are open at the bottom, and that over each oisaid central depressions a cup, d* di d3, lite., is secured, as shown in the drawing. These'cups rest upon pins or studs f, rising from circular shelves H, which are attached to the interior of the rectifier, and which are depressed'towards their centres, where4 they are provided with apertures for the upward passage ofthe vapors and for the downward passage of the low-wine resulting from the condensation of a portion of said vapors. The low-wine dripping down over the dishes Dl D2 D3, Svc., and over shelves H, collects in the cups al1 d2 d3, Ste., and if these cups are full, it overows and inally passes 'down through the pipe g in the receiver A. The rectifier is,4 provided with three (more or less) Water-jackets,

I Il I2, which are filled with water, `so as to promote the condensation of a ortion ofthe vapors passing up through the rectifier. Ihemanner in which the water-jackets are supplied with water will be presently explained. The top plate 7i ofthe receiver G is perforatedin its centre with a circular aperture, h', through which the vapors pass up into theuidditional rectifier G. The bottom part of this additional rectifier is occupied 'by a water chamber, J, which is'supplied withwater through one or more pipesj, an'd'from which the surplus water passes olf through overilow-pipes j. wThese overflow-pipes lead down to the water-jacket Il, which is provided with an overflow-channel, k, through which the water passes down into thcjacket I, and ifthis jacket is full, the water llows through the overdow-pipe Zinto the vessel E on the top of the receiver A. By these means the water which is admitted cold into the chamber J, is gradually .warmed as it passes down through the'jackets Il, I, .and the vessel E, and its cooling effect is proportionately diminished, so thatthe heaviest vapors -will condense below, and as the remaining vapors rise, the condensation ex tends gradually to lighter vapors. Above the water-chamber J, in the additional rectifier G, are two or more dishes K,`with anrintervening shelf, L, and each of the dishes is provided with a central depression, m, from which descends a tube, 4n, so that the 10W-wine, which results from the condensation of aportion ofthe vapors passing through the additionalrectifier, drops down over the dishes K, and through thedepressions m and tubes n, into the upper cup djn the rectifier G. VOn the top of the additional rectifier Gis a water vessel, L, which is supplied with cold Water from a. suitable reservoir, and from which the water overflows through a channel, o, which leads down into the upper water-jacket I2 of the rectifier G. The light vapors which will not condense in the rectiers G G pass o through the pipe M, which connects with a cooler or condenser of anyr suitable construction'. Y m i In this apparatus it has been found that the impurities contained in the liquid nreliable to form a deposit in the cups d* did, Ste., andheretofore no means were provided to remove this deposit. This defect Ihave amended by my present improvement. I'have applied a pipe, Ppprovided with.branchpipes pl p p3, dto., which communicate with the cups all d2, 55e., close doiv'n to their bottoms, and which are provided with suitable stop-cocks, so that they can be opened or closed. at the will of thc operator. I The pipe P is provided with a funnel-shaped mouth, so'that it can be readily filled with water, andby manipulating the stop-cocks in the branch pipes, each of the cups dl d2 d, Snc., can be' Hooded with water, and Washed out with ease aud facility.

What I claim as new, and desire to secure by Letters Patent, is- The blow-ofi` pipe P, in combination with the cups Z1 d2 d d? in the rectier G, substantially as and for the purpose described.
